•Problem: Bluetooth serial port was disconnected automatically.

Solution: When any serial-based connection is established, an inactivity timer starts. If no application opens the port, the connection is ended automatically. This is a normal characteristic of the serial-based connection and is not a defect. If you need the Bluetooth serial port, just reconnect it.

•Problem: PIM Synchronization failed with an error message “The Synchronization with xxx (Bluetooth device name) failed. PIM (Personal Information Manager) Interface failed.”
